BackgroundProximal humeral fractures (PHFs) are among the most common fractures in elderly patients, but there is insufficient evidence from randomized controlled trials (RCTs) to determine which interventions are the most appropriate for their management. To date, no RCT has directly compared reverse shoulder arthroplasty (RSA) with nonoperative treatment for 3- or 4-part PHFs in elderly patients.MethodsThis was a prospective RCT. The primary objective was to compare pain and function 12 months after fracture using the Constant score in patients aged 80 years or older with 3- and 4-part PHFs, treated by either RSA or nonoperative treatment. Secondary outcome measures included Disabilities of the Arm, Shoulder and Hand, visual analog scale (VAS), Short Form 12 (SF-12), EuroQol 5 Dimensions, and EQ-VAS scores.ResultsWe analyzed 30 nonoperative and 29 RSA patients with mean ages of 85 years and 82 years, respectively. No differences between the nonoperative and RSA groups were noted for any patient-reported outcomes at 12 months' follow-up except the VAS pain score. The Constant scores were 55.7 in the nonoperative group and 61.7 in the RSA group (P = .071); the Disabilities of the Arm, Shoulder and Hand scores were 29 and 21, respectively (P = .075); the VAS scores were 1.6 and 0.9, respectively (P = .011); the physical SF-12 scores were 36 and 37, respectively (P = .709); the mental SF-12 scores were 43 and 42, respectively (P = .625); the EuroQol 5 Dimensions scores were 0.89 and 0.92, respectively (P = .319); and the EQ-VAS scores were 65 and 67, respectively (P = .604).ConclusionsThis study yields important evidence for the treatment of complex PHFs in elderly patients suggesting minimal benefits of RSA over nonoperative treatment for displaced 3- and 4-part PHFs. At short-term follow-up, the main advantage of RSA appeared to be less pain perception.Copyright © 2019 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.
